A) Relational Database
B) Hierarchical Database
C) Flat File Database
D) Object-Oriented Database
Correct Answer: C) Flat File Database
Explanation: Flat file databases store data in a simple, one-dimensional format, usually as plain text files, and are often used for smaller or simpler data sets.
Question 03
Which component of a CPU performs mathematical and logical operations?
A) Control Unit
B) Arithmetic Logic Unit
C) Register
D) Cache
Correct Answer: B) Arithmetic Logic Unit
Explanation: The Arithmetic Logic Unit (ALU) in a CPU is responsible for performing mathematical calculations and logical comparisons.
Question 04
What does TCP/IP stand for?
A) Transmission Control Protocol/Internet Protocol
B) Transfer Command Protocol/Internet Process
C) Transaction Control Program/Internal Packet
D) Transfer Control Protocol/Internet Path
Correct Answer: A) Transmission Control Protocol/Internet Protocol
Explanation: TCP/IP (Transmission Control Protocol/Internet Protocol) is the suite of communication protocols used for transmitting data over the internet.
Question 05
Which type of database model organizes data using a parent-child relationship, often represented as a tree structure?
A) Relational Database
B) Flat File Database
C) Hierarchical Database
D) NoSQL Database
Correct Answer: C) Hierarchical Database
Explanation: A hierarchical database organizes data into a tree structure, with each record having a parent-child relationship.
Question 06
Which type of software provides a trial version and requires a purchase for full functionality?
A) Freeware
B) Shareware
C) Open Source
D) Proprietary Software
Correct Answer: B) Shareware
Explanation: Shareware provides users with a trial version and requires a purchase or subscription to access the full functionality of the software.
Question 07
What type of backup captures only the changes made since the last backup of any kind?
A) Full Backup
B) Incremental Backup
C) Differential Backup
D) Mirror Backup
Correct Answer: B) Incremental Backup
Explanation: Incremental backups only capture the data that has changed since the last backup, regardless of whether it was a full or differential backup.
Question 08
What is the main purpose of a project’s analysis phase in the SDLC?
A) To implement the system
B) To determine user requirements
C) To conduct beta testing
D) To install hardware
Correct Answer: B) To determine user requirements
Explanation: During the analysis phase of the System Development Life Cycle (SDLC), the focus is on understanding user needs and requirements for the new system.
Question 09
Which memory type is non-volatile and retains its content even when the computer is powered off?
A) RAM
B) Cache
C) ROM
D) Registers
Correct Answer: C) ROM
Explanation: ROM (Read-Only Memory) is non-volatile memory that retains its content even when the computer is turned off, unlike volatile memory like RAM.
Question 10
Which network topology features devices connected along a single cable?
A) Mesh
B) Star
C) Ring
D) Bus
Correct Answer: D) Bus
Explanation: In a bus topology, all devices are connected along a single cable, which serves as the communication backbone.
Question 11
What does the command SELECT in SQL do?
A) Insert new data into a table
B) Modify existing records
C) Retrieve data from a database
D) Delete data from a table
Correct Answer: C) Retrieve data from a database
Explanation: The SELECT command in SQL is used to query and retrieve data from one or more tables in a database.
Question 12
What is the purpose of the control unit in a CPU?
A) Execute arithmetic operations
B) Manage system memory
C) Fetch instructions and direct operations
D) Store temporary data
Correct Answer: C) Fetch instructions and direct operations
Explanation: The control unit retrieves instructions from memory and directs the operation of the CPU, telling other components how to process data.
Question 13
Which type of encryption uses two keys, one public and one private?
A) Symmetric Key Encryption
B) Asymmetric Key Encryption
C) Hashing
D) Digital Signature
Correct Answer: B) Asymmetric Key Encryption
Explanation: Asymmetric key encryption uses two keys—a public key for encryption and a private key for decryption—ensuring that only the recipient can decrypt the message.
Question 14
Which type of backup takes less time by only backing up data that has changed since the last full backup?
A) Incremental Backup
B) Full Backup
C) Differential Backup
D) Mirror Backup
Correct Answer: C) Differential Backup
Explanation: A differential backup captures all changes made since the last full backup, taking less time than a full backup but more than an incremental backup.
Question 15
What is the role of a device driver in a computer system?
A) Manage internet connections
B) Translate high-level code into machine code
C) Provide an interface between hardware and the operating system
D) Store temporary data
Correct Answer: C) Provide an interface between hardware and the operating system
Explanation: Device drivers are programs that allow the operating system to communicate with hardware devices, translating OS commands into hardware-specific instructions.
Question 16
Which of the following is a key characteristic of open-source software?
A) It is free to use, but the source code cannot be modified
B) It is free to use, and the source code can be modified
C) It is available for a free trial, but requires purchase for full features
D) It is proprietary and cannot be distributed freely
Correct Answer: B) It is free to use, and the source code can be modified
Explanation: Open-source software is free to use, and users are allowed to modify and distribute the source code.
Question 17
Which component of a computer is considered volatile memory?
A) ROM
B) SSD
C) RAM
D) Hard Drive
Correct Answer: C) RAM
Explanation: RAM (Random Access Memory) is volatile, meaning its contents are lost when the power is turned off.
Question 18
Which of the following describes the role of a database administrator (DBA)?
A) Design websites
B) Maintain hardware components
C) Manage and configure databases
D) Develop mobile applications
Correct Answer: C) Manage and configure databases
Explanation: A database administrator (DBA) is responsible for maintaining, configuring, and securing databases within an organization.
Question 19
What does a compiler do in software development?
A) Translates source code into machine code all at once
B) Executes code line-by-line
C) Interprets user commands
D) Debugs program errors
Correct Answer: A) Translates source code into machine code all at once
Explanation: A compiler translates the entire source code into machine code before execution, unlike an interpreter which translates code line-by-line.
Question 20
Which backup strategy requires both a full backup and the most recent incremental backups for recovery?
A) Full Backup
B) Differential Backup
C) Incremental Backup
D) Mirror Backup
Correct Answer: C) Incremental Backup
Explanation: To restore from an incremental backup, you need both the full backup and all subsequent incremental backups.
